ALAMEDA, Calif. -- Minutes after selecting Buffalo linebacker Khalil Mack with the fifth pick of the 2014 NFL draft, Oakland Raiders general manager Reggie McKenzie was asked if he thought his quarterback of the future might still be available.

Mind you, this was when Blake Bortles had been the only quarterback taken.

“Yes,” McKenzie said softly, “there’s an opportunity for that. Yes.”

So by the time the dust cleared on the first round Thursday night, Bortles, who was taken third overall by the Jacksonville Jaguars, was joined by Johnny Manziel, who fell to 22^nd and the Cleveland Browns, and Teddy Bridgewater, who went 32^nd in the final pick of the night to the Minnesota Vikings, who traded up to get him.

Might Fresno State’s Derek Carr, who has long been linked to the Raiders, still be on the docket when Oakland is scheduled to make the fourth pick of the night, No. 36 overall, or will the Houston Texans, who badly need a quarterback and lead off the second round, make it a family affair by drafting the younger brother of the man they made the first overall pick in 2002, David Carr?

From the Raiders’ perspective, it’s no secret they believe they are set with Matt Schaub for at least the next two years, and they even feel comfortable with backups Matt McGloin and Trent Edwards. But the feeling is also they would like to draft a project in the middle rounds, someone like Pittsburgh’s Tom Savage. Currently, the Raiders’ fourth-round pick is at No. 107 overall.

One plausible scenario has the Raiders, who do not have picks in the fifth or sixth rounds but hold three in the seventh, trading back in the second round to acquire more selections, especially if they are not truly in love with a player at No. 4 in the second round today.

McKenzie, though, said “no deal was presented, only interest” for the No. 5 overall pick on Thursday. With it not clear if there will be a market today for the Raiders’ second-rounder, they have options.

Mack certainly addressed a need and was the best player available as well.

So, besides Carr, who passed for 5,082 yards with 50 touchdowns and eight interceptions and completed 68.7 percent of his passes in 13 starts last season, who is a potential target for the Raiders in the second round?

Here is a look at five possible prospects:

USC receiver Marqise Lee was the 2012 Biletnikoff Award winner as a sophomore, but had a down junior year. At just under 6-foot and 192 pounds, there are questions about his durability, but he is a playmaker after the catch.

Alabama offensive tackle Cyrus Kouandjio is massive at 6-7, 321 pounds, but there are concerns about his surgically repaied knee. He is considered an ideal fit to work in a power-blocking scheme.

Minnesota defensive tackle Ra'Shede Hageman is a disruptive if inconsistent force at a tick under 6-6 and 310 pounds. His athleticism might force a move to defensive end.

Utah cornerback Keith McGill is big at 6-3, 213 pounds, and his long arms make him an ideal fit for press coverage. Still, he only had one interception in two seasons for the Utes.

Nebraska cornerback Stanley Jean-Baptiste is also big for the position at 6-3, 218 pounds and had seven interceptions in 19 starts for the Cornhuskers.
